2 Claims. (Cl. 15-'569) This invention relates to a fluid applicator andmore particularly to a novel dauber for use in applying cos- 'metics ormedications on the person of the user or for applying oils, lubricants,polishes or the like, on any suitable .surface.

An object of this invention resides in .the provision of meansfacilitating the application of cosmetics or medications on the personof the user.

A further object of the invention resides in the provision of meanscontrolling the flow of fluidthrough a dauber so that the harder'thedauber is pressed against the 'surface'being treated, themore fluid ispermitted to flow through the valve utilized therein.

A further object of the invention resides in the provision'of a dauberemploying a novel valve structure in which a valve member iscontinuously urged against a valve seat by means of resilient legs,which resilient legs are secured to an insert or retaining ring fittedin the neck of the container.

Yet another object of the invention resides in the .provision of meansaflfording protection for the surface a of the body of the user applyingthe dauber by providing a soft and rather large area contact for thedauber, yetproviding better control for the flow of fluid from thedauber by employing a mechanical'valve structure.

In the past, daubers have been produced which employed one or morelayers of foam rubber at the ends thereof through which fluid flowed.However, these former daubers are unsatisfactory since the flow of evenlight-weight fluid therethrough is severely restricted and the daubersare completely unsatisfactory for heavier or thicker fluids.

Other daubers have been produced which employ a mechanical valve butthese daubers generally have a reduced contact end, which often causessevere discomfort to the user since the amount of pressure required foractuating the valve member is applied over a minimum surface area of theskin of the user.

Therefore, it is a yet further object of the present invention toprovide a dauber eliminating all of the aforesaid disadvantages of priorart daubers yet which is inexpensive to manufacture, simple to use,eflicient in operation, capable of being used with liquids of variousviscosities, and which is attractive in appearance.

These, together with the various ancillary objects and features of theinvention, will become apparent as the following description proceeds,are attained by this dauber, preferred embodiments of which have beenillus trated in the accompanying drawings, by way of example only,wherein:

With continuing'reference to the accompanw'ng drawings wherein likereference numerals designate'similar parts throughout the various views,reference numeral 10 generally designates the dauber comprising thepresent invention, which includes a fluid container formedications,rco'smetics, or the like, such as skin bracers or tonics,lotions or perfumes, fungicides, etc.

Thecontainer 12 is provided with external threads at 14 on which a cap16 isiadapted to be readily secured. 'I'he retaining'ring '18'forming aninsert is, forced within the neck 20 of the container 12, the retainingring 18 preferably .being integrally molded of any suitable materialincluding synthetic plastic resin or 'the like. Fitted within aninnerflange not :the retaining ring 18 is a valve seat24 having atapered surface'26 cooperating with thefco'nical porti'on.28 of a valvemember The valve member 30 is provided with adownwardlyextendin'gportiojn 32'having a series of grooves 34'thereinallowin g ready flow of'fluid therein when the valve member is in' anopen position andthe surfaces 26 and. 28 are spaced.

The retaining ring 18 is provided with 'aportion of enlargedcross-sectional area formingan inner "peripheral flange on shoulder 36against which the valves'eat24 abuts. The flange, 36 defines aperipheral 'aperture-75.

The valve member 30 includes'a plurality'of legs 38 of a resilientspringy material 'chosenfrom any'suitable syntheti'c'resin'or the likeand which as'is shownLinFig. 4 may conform'in .contour to the icontourof the projection 40 of the 'retainingring 18, thus being arcuate inshape and engaging the retaining ring overalarge surface area. Theprojection 40may have a molded rim as at 42 at the lower end thereof or,optionally, the lower end may be swaged. over thetip endsv of the legs38 to securely hold the legs '38 in place. 'Ihe legs may be molded in .aunitary manner including a center piece 44 which in turn may beintegrally formed with-the other .portion of the valve member 30, orwhichmay'beheld thereto by-me'ans of nut and' bolt 46 and48,'respec'tively.

In addition to the inner flange 22, which may be of cylindricalconfiguration and which may be provided with a recess 50 therein as wellas a shoulder 52, is an outer flange 54. Positioned between the outerflange 54 and the inner flange 22 is a cover 56 formed of a disk 54 ofporous material, such as foam rubber or the like.

A layer of fabric 60 porous, and relatively soft and smooth surfacedoverlies the foam rubber 54 to prevent deterioration thereof. The flange54 is crimped or swaged in such a manner that it holds the peripheraledges between the inner and outer flanges 22 and 54, respectively, in asecurely locked manner within the arcuate surface of the outer flange54, providing a smooth contact surface.

In operation, the fluid in container 12 will pass through the valve whenthe cover 56 is pressed against the valve member 30 so as to move thesurface 28 away from the surface 26 allowing fluid flow. This will causethe legs 38 to how after being placed under compression. As soon as thevalve member is released, the legs will force it backinto a closedposition. Fluid flowing into the space 62 between the cover 56 and thevalve member 30 3 and valve seat 24 will pass through the porous cover60 onto the skin of the user or onto any other surface being treated.Hence, the greater the compression of the valve, the greater the fluidflow.

In Fig. 5 there is shown a modified form of the invention in whichconical valve member 80 cooperates with a conical surface 82 of a valveseat 84. The valve member 82 is integrally formed with the legs 86 whichcorrespond to the legs 38, it being noted that the valve seat 84 isprovided with an enlarged passage 88 so that the conical head of thevalve member 80 can pass therethrough.

In Fig. 6 there is shown a yet further form of the invention in whichthe valve seat 90 is provided with a groove 92 therein so that fluidentering into the space corresponding to the space 62 between the coverand the valve seat will flow into the reservoir 92 when the dauber is inan upright position, permitting an immediate source of fluid to beavailable and to soak through the foam rubber cover, even prior todepression of the valve member.

In Fig. 7 there is shown a modified form of means for holding the cover56 in place, which includes the concept of forming the inner flange 100and then swaging the outer flange 102 to form a shoulder 104 whichclampingly engages the cover 56 holding, holding the cover between theshoulder 104 and the flange 100.

Thus, it can be seen that there has been provided a dauber or applicatorincluding a fluid container 12 having a neck terminating in an open end.A retainer ring or insert 18 having a projecting portion 40 is fitted inthe neck. A porous resilient cover 56 is secured to the ring 18 and avalve seat 24 is fitted in the ring with a valve member 30 being movablewith respect to the valve seat 24 secured to the projecting portion bymeans of a rim 42. The valve member 30 cooperates with the valve seat 24to control the flow of fluid from the container 12 to the cover 56 whichis depressable into engagement with the valve member 30 to move thevalve member to an open position.

Various changes and modifications may be made without departing from thespirit and scope of the present invention and it is intended that suchobvious changes and modifications be embraced by the annexed claims.
